This assumes scarce chips with unforgeable, nonexportable keys and unique certificates; a compromised manufacturer can mint fake chips.","stamp":2,"from":"poa12Mh5yqFkExNvNWTLogZUqk9PP4PwsBb4XAhSXxoPuwBj","nonce":9,"parents":["b266bbfec9ea77af1a0cbcc885e9be0365601c92afb97a368639a44aeb416062","aabef6e75bb141486501ca9b0c634d46e7e3fa08da40547408a0e02131f2fbcd"],"ts":1793034743,"cid":"poa-mainnet-1","sig":"2CA31QLK7uBvBpCZmxFZReTYm1W7jw39ry6DT37ojrpPF6KwHhpHHrXb4P6UTRz93hXQqXN9venSArmnLzQYvmLm"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T15:13:09.146Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
